PWA not working

[VittorioAccomazzi]

I'm not able to get the service worker registering correctly with this template. Here are the steps to reproduce the problem :

• install the template npx create-react-app@5.0.0 my-pwa --template redux-typescript
• edit index.tsx to enable the service worker at line 21 as follow : serviceWorker.register();
• build the application npm run build
• serve the application with serve : serve -s build

The service workers are not installed, this is visible either setting a breakpoint as well as checking with Chrome's developer tools.

the registration fails at this line:

and the reason is that the file service-worker.js is not found and serve just sent the index.html file. So the problem is somewhere in the compilation step.

Any serviceworker setup is really part of Create-React-App's config - you might want to check over in that repo.

Thank you @markerikson. Indeed Create-React-App has changed, a solution to this problem is posted here.
